Null Modem DB9 cable

by
Uki D. Lucas

When connection the i.MX6 micro-computer "Debug" cable to Mac's Serial to USB I need to use DB9 cable with female on both ends. As I found out a simple "Mini Gender Changer" (gender-bender) will NOT do, you need a "Null Modem" cable.

I will provide pin-put diagram shortly, but as I understand at least pins 2 and 3 are reversed. Later I will Ohm-out the pins and build myself a smaller version of what is pictured above.
